| 摘要 |
The invention relates to a device for the optical detection of a gas in an observed spatial area (20), comprising a camera (22) and means for the continuous detection of at least one gas in the area observed on the basis of an analysis of absorbency in a plurality of different spectral bands. The device also comprises a matrix of micromirrors (14) that can be individually oriented between at least two positions wherein, in a first position, they deflect the radiant flux (16) from the observed area towards the camera (22) for the detection of gas in said spectral bands, and in a second position, they deflect the radiant flux (16) from the observed area towards a Fourier-transform infrared spectroscope (24). |
